摘要/Abstract

摘要： 以1,3:2,4-二(3,4-二甲基卞叉)-D山梨醇（DMDBS）为凝胶因子，三硬脂酸甘油酯（GT）为相变材料，制备了一系列不同DMDBS含量的GT/DMDBS复合相变材料。通过测试凝胶-溶胶转变温度和泄漏量，发现凝胶因子DMDBS能够定形GT，当GT中添加3%（质量分数）DMDBS时，凝胶态复合相变材料的凝胶-溶胶转变温度为159 ℃，泄漏量仅为6%。通过SEM观察了凝胶复合材料和干凝胶的表面微观结构。通过DSC分析了复合相变材料的热性能，其中GT/3%DMDBS复合相变材料的熔化焓和凝固焓分别为126.4 J/g和105 J/g。通过激光热导仪测试样品导热系数。通过紫外吸收光谱和红外吸收光谱研究了DMDBS在GT中自组装形成三维网络结构的驱动力。通过XRD表征了DMDBS的添加对GT分子结构的影响。

Abstract: A series of glyceryltristearate (GT)-1,3:2,4-di-(3,4-dimethyl) benzylidene sorbitol (DMDBS) composite phase change materials (PCMs) were prepared with the DMDBS as a gelator and GT as the PCM. Through examining the gel-sol temperature and the leakage of the PCM composites, we found that the composite PCM can be form-stable. A 3%(weight ratio) of DMDBS addition to the formulation gave a gel-sol transformation temperature of 159 ℃ and the resulted leakage was only 6%. Scanning electron microscopy (SEM) analyses were performed to observe the surface microstructure of the composites and the xerogel. The thermal properties were studied by Differential scanning calorimetry (DSC). The results indicated that the melting and freezing enthalpy of GT-3%DMDBS composite were 126.4 J/g and 105 J/g, respectively. A laser flash diffusivity apparatus was used to measure the thermal conductivity of samples. The driving force of the formation of the three-dimensional network structure due to DMDBS was studied by UV absorption spectrum and IR absorption spectrum. The effect of DMDBS addition on the molecular structure of GT was characterized by X-ray diffraction (XRD).
